标准摘要
[中文适用范围]: 本文件适用于具有以下特性的个人剂量计: a) 佩戴在躯干、靠近眼睛或四肢上 b) 测量个人剂量当量Hp(10)、Hp(3)和Hp(0.07),来自外部X射线、伽马射线、中子(不包括Hp(3))和β辐射,并可测量相同辐射的个人剂量当量率(用于报警目的) c) 具有数字显示。该显示可以连接也可以不连接 d) 具有个人剂量当量或个人剂量当量率的报警功能,混合剂量计除外。对于混合剂量计,个人剂量当量的报警功能应在相关读出系统中实现 注1 本文件中提到的“剂量”是指个人剂量当量,除非另有说明 注2 本文件中提到的“剂量计”包括所有个人剂量计,除非另有说明 注3 本文件不涵盖用于Hp(3)测量的中子剂量计 本文件规定了剂量计及其相关读出系统(如提供)的要求。 通常,剂量计无法测量上述所有量。因此,剂量计仅针对其预期使用的量和辐射类型进行测试。其他类型的辐射被视为影响量,也可能有要求。 本文件规定了上述剂量计的通用特性、通用测试程序、辐射特性以及电气、机械、安全和环境特性。对相关读出系统的唯一要求是影响其个人剂量当量和报警设置读取精度的要求,以及影响剂量计的读取器的要求。 本文件不涵盖事故或应急剂量测量的特殊要求,尽管剂量计可用于此目的。 本文件不适用于测量脉冲辐射的剂量计,如来自许多医疗诊断X射线设备、线性加速器或类似设备的辐射。 注4 用于电离辐射脉冲场的剂量计的要求和测试程序可在IEC TS 63050或IEC TS 62743中找到 本文件不适用于测量环境或方向剂量当量的剂量计。 注5 环境或方向剂量当量计的要求可在以下标准中找到:IEC 60846-1;IEC 62387、IEC 61017或IEC 60532。 [外文原描述]: IEC 61526:2024 applies to personal dosemeters with the following characteristics: a) They are worn on the trunk, close to the eye, or on the extremities. b) They measure the personal dose equivalents Hp(10), Hp(3), and Hp(0,07), from external X and gamma, neutron (not for Hp(3)), and beta radiations, and may measure the respective personal dose equivalent rates for the same radiations (for alarming purposes). c) They have a digital indication. This indication may or may not be attached. d) They have alarm functions for the personal dose equivalents or personal dose equivalent rates except for hybrid dosemeters. For hybrid dosemeters an alarm function for the personal dose equivalents shall be implemented in the associated readout system. This document specifies requirements for the dosemeter and, if supplied, for its associated readout system. This document specifies, for the dosemeters described above, general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and environmental characteristics. This edition includes the following significant technical changes with respect to the previous edition: a) Modification of the title; b) Inclusion of the measurement quantity for the dose in the lens of the eye, Hp(3); c) Inclusion of measurement quantity for dose in the skin and extremities, Hp(0,07); d) Inclusion of dosemeters between active and passive: "hybrid dosemeters"; e) Inclusion of software requirements; f) Harmonization of requirements for linearity to IEC 62387; g) Revised neutron energy response requirements.
